Subject: Makefile changes to make building *-clang-debug easier
Hi all,
currently, -faddress-sanitizer is used for the *-clang-debug builds.
But clang 3.2 complains that this option is deprecated, and suggests
using -fsanitize=address instead.
I am, however, not sure whether or not older clang versions support
-faddress-sanitizer, but not -fsanitize=address.
Due to https://bugzilla.redhat.com/show_bug.cgi?id=949489, none of these
options can be used on Fedora 18.
That's why I decided to patch Makefile and introduce a new variable,
CFLAG_SANITIZE_ADDRESS.
I also changed the default from the old -faddress-sanitizer to the new
-fsanitize=address.
This might destroy backwards compatibility, so I am not sure whether I
should send a pull request for unstable.
That's why I just attach the patch.
OTOH, the *-clang-debug targets are intended for developers, not for end
users. They are not even mentioned when just using "make".
What do you think?
Frank
